8 GB VRAM59 TOOLS FIT THIS TIER

AI tools that run on 8 GB VRAM

Eight gigabytes is a practical hobbyist entry tier, not a universal compatibility line. Many image workflows and compact quantized LLMs fit with sensible settings. Official ComfyUI documentation also shows a Wan 2.2 TI2V 5B path designed for 8 GB with native offload; larger video variants remain a different workload.

Capabilities

✓ WHAT YOU CAN RUN

  • SDXL comfortably in ComfyUI / A1111 / Forge
  • Flux.1 [dev] FP8 with offload
  • Selected small-to-mid quantized LLMs with context sized to available memory
  • IPAdapter + ControlNet on SDXL
  • Image upscaling pipelines

✕ WHAT STAYS OUT OF REACH

  • Large video variants, high resolution, or long frame sequences
  • Comfortable large-model LoRA training without aggressive memory-saving settings
  • High-concurrency LLM serving with substantial KV cache

VRAM tier ≠ universal guarantee

These are planning envelopes. Model variant, precision, resolution, frame count, context, cache, runtime, and offload can move the same workload across tiers. The guide shows how to validate a real ComfyUI graph before buying hardware.
